## Description

- description: Expanding the performance of field-effect devices is a key challenge
    of the ever-growing chip industry at the core of current technologies1. Non-volatile
    multiferroic transistors that control atomic movements rather than purely electronic
    distribution are highly desired2. Recently, a field-effect control over structural
    transitions was achieved in commensurate stacking configurations of honeycomb
    van der Waals (vdW) polytypes by sliding boundary strips between oppositely polarized
    domains. This ferroelectric hysteretic response, however, relied on pre-existing
    dislocation strips between relatively large micron-scale domains, severely limiting
    practical implementations. Here we report the robust electric switching of single-domain
    polytypes in nanometre-scale islands embedded in super-lubricant vdW arrays. We
    etch cavities into a thin layered spacer and then encapsulate it with functional
    flakes. The flakes above/under the lattice-mismatched spacer sag and touch at
    each cavity to form islands of commensurate and metastable polytype configurations.
    By imaging the polarization of the polytypes, we observe nucleation and annihilation
    of boundary strips and geometry-adaptable ferroelectric hysteresis loops. Using
    mechanical stress, we further control the position of boundary strips, modify
    marginal twist angles and nucleate patterns of polar domain. This super-lubricant
    arrays of polytype (SLAP) concept suggests ‘slidetronics’ device applications
    such as elastic-coupled neuromorphic memory cells and non-volatile multiferroic
    tunnelling transistors and programmable response by designing the size, shape
    and symmetry of the islands and of the arrays.
